When using pellet grills regularly you may notice smoke coming from the hopper once in a blue moon. This is usually a warning sign for a couple of different issues, and today we’re walking you through what you should do if you see smoke coming from the hopper.
What is the most common cause of pellet grill hopper smoke?
When a small amount of smoke is coming from your hopper while cooking there is likely a small air flow issue. This can be caused by your grill being placed on an uneven surface, blockage in your vents, excessively high winds or a malfunction in the fan.
If this is the first time you’ve used your grill and you’re noticing smoke coming from the hopper, begin the shutdown process and call customer service for more assistance. They will walk you through a troubleshooting process to diagnose the issue.
What to do when I see a small amount of smoke coming from my hopper?
If this is not the first time you’ve used your grill, then the hopper smoke is likely a maintenance issue.
The first thing to do is ensure your grill is on a level surface and make sure your vents are clear of obstructions. If you can tell there is excessive wind blowing into the vents of your grill, reposition it so that does not happen. Remember, your vents should have nearly an inch of space for smoke egress at least.
Monitor your grill for the next 10 minutes and watch to see if the hopper smoke dissipates. While watching, listen for a light “whirring” of a fan blade from the hopper of your grill. If the smoke does not dissipate after 10-minutes, then begin the shutdown process.
If you did not hear the fan “whirring” during the monitoring period, contact customer service for troubleshooting steps to diagnose the issue.
If you did hear the fan “whirring” then the issue is likely caused by a buildup of ash in the bottom of the grill, or a buildup of pellet dust in the auger tube. Allow your grill to cool down then give it a full and complete cleaning.
Once cleaned, fire up the grill and monitor it for hopper smoke again. If it has returned, contact customer service at 616-392-7410 for the next steps.
What to do if the hopper is smoking during shutdown?
If you notice smoke is coming from your hopper during the shutdown process, or even after the grill is completely shut off, then you are likely dealing with a backburn.
A backburn is when pellets or pellet dust within the auger catch fire and smoke begins to creep out of the hopper.
If you believe you’re dealing with a back burn, turn the grill back on and set it to the lowest temperature setting on PID mode. This will continually feed pellets into the fire at a set rate, lowering the temperature and hopefully pushing out the burnt pellets.
Once the grill has achieved a temperature of under 200F, begin the shutdown process again.
What to do if smoke is billowing from my hopper?
If you’re noticing a large amount of smoke coming from your hopper then you are likely dealing with a serious backburn. This is almost always caused by poor-quality pellets breaking down in the auger leading to a buildup of dust. That dust can ignite, leading to a fire that burns into the hopper.
If you’re absolutely sure your grill is experiencing this type of backburn, follow the next steps safely if you feel comfortable doing so.
- Immediately unplug the grill and ensure the hopper lid and grill lid are both closed.
- If possible to do so safely, reposition the grill away from nearby flammable objects.
- Keep both the grill and hopper lid closed to starve the fire of oxygen.
- Once the grill is cooled down, remove all pellets from the grill and perform a full and complete cleaning of the grill.
